Vortex Strike

You brandish the weapon used in the spell’s casting and throw it up to 30 ft away in a line. While on its way, the weapon is propelled by arcane power and starts to spin, hitting any creature in its path as if it were a regular melee weapon attack applying the weapon attack’s normal effects. After reaching its destination it magically reappears in the casters hand.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, each creature hit suffers an extra 1d6 force damage for each slot.
